GRAPHOPHONE ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 778,434, dated December 27, 1904.

Application filed November 30,1903. Serial No. 183,266.

To @ZZ whom, t 7am/ zj concern:

Be it known that I, JOHN A. VVOZENCRAFT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Alarm-Clocks",of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufio iicient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to alarm-clocks wherein there is a time-train and an alarm-train act- [5 ing independently of each other, but so related that-the alarm-train can be set to be released ata determined time, as indicated by the i time-train.

rIhe object of this invention is to obtain an zo alarm-clock in which the alarm-train will be released and actuated relative to the timetrain of the clock in the ordinary way and by which the alarm given will consist in words spoken or shouted by a phonograph forming the signal of the alarm-train.

A further object of this invention is to obtain a clock of the kind named wherein the words or sentences spoken or shouted may be repeated several times unless the alarm-train 3o of the clock be stopped.

A further object of the invention is to construct an alarm-clock of the kind named which will occupy but little space in addition to that now required for alarm-clocks of the ordinary 3 5 kind.

A further object of the invention is to obtain an alarm-clock of the kind named which can be regulated to run at the proper rate of speed to substantially reproduce the tones of the voice of the person making the record.

In the drawings accompanying and forming a part hereof, Figure l is a front elevation of a clock embodying this invention. Fig. 2 is a side elevation of a clock embodying this invention. Fig. 3 is a rear elevation of a clock embodying this invention, and Fig'. 4 is an elevation of the governor or regulator of the alarm-train of the clock. Fig. 5 is an elevation of the time-train and alarm-train of the clock removed from the casing. Fig. 6 50 is a top plan view of the casing of the spring and train actuating the phonograph of the apparatus with a portion of such casing broken away to expose the several parts to view. Fig. 7 is a vertical sectional view of the hol- 55 lowY shaft on which the hub of the cylinder `containing the phonographic record is rotatably mounted, such figure showing a section of the back plate of the clock and one end of the center shaft thereof. 6o

A reference letter used to designate a given part is employed to indicate such part throughout the several figures of the drawings whereever the same appears.

A is a clock.

B B are the hands of the clock. An ordinary independent time-trainas, for instance, one comprising' spring I) on shaft o', driving'- wheel b2, center shaft b3, on which are mounted the hands of the clock, and wheel l, pinion 7o b5, intermeshing with wheel o", such pinion mounted on shaft o, gear-wheel o7, also mounted on shaft o, pinion bs, intermeshing with wheel L7 on shaft 7), gear-wheel 610 on shaft o, pinion ou on shaft 612, such pinion interrneshing with wheel om, escape-wheel Z213 on shaft om, balance-wheel L, and lever connection L between the escape-wheel om and such balancewheel fand alarln-trainas, for instance, one comprising spring /w and driving-wheel SO Z117 on shaft L, pinion Ll" on shaft L20, such pinion engaging with the driving-wheel gear-wheel L on shaft L pinion Zr on shaft e', engaging with gear-wheel b21, pinion of on shaft 52", engaging with gear-wheel om, gear- 8 5 wheel o2, also mounted on shaft If, and pinion If", mounted on shaft aare contained in the clock and the ordinary connection between the alarm-train and the time-train of the clock is used. No invention is claimed therefor, and spring or other motors may be used to actuate such trains, respectively, as preferred.

C is a cylinder connected to vhub f by arms F F, such hub being rotatably mounted on hollow shaft I) and such hollow shaft positioned so that the cylinder is concentric to the hour and minute hands of the clock. Shaft D is made hollow, so that the hands of the clock can be set by a key inserted through the central hole F of such hollow shaft in that class of clocks set by a key from the back.

F F are arms extending from the hub f to the rim forming cylinder C. Hub f turns on hollow shaft D.

Cylinder C when mounted as described is concentric to the dial of the clock, and when round case G is used to inclose the clock, as is illustrated in the drawings, such cylinder is also concentric with such round case.

H is a belt-pulley rigidly mounted on the hub f.

I is a belt-pulley rigidly mounted on rotatable shaft f/ of the alarm-train of the clock.

J is a belt connecting' pulleys H and I and transmitting motion from the pulley I to the pulley H and cylinder C. Hub f and arms F F are positioned with reference to the back plate of the clock, so as to permit the winding-keys K and L to be placed in position, as shown, without interfering' with the rotation of the hub and arms.

M M are weights mounted on the springarms N N, (see Fig'. 4,) respectively, on shaft 12,. Shaft n is one of the rotatable shafts of the alarm-train of the clock.

O is a disk loosely mounted on shaft a to move longitudinally on such shaft, and one end of each of the respective spring-arms N N is attached to such disk. The opposite ends of such spring-arms are respectively attached to the shaft 71 so that as such shaft is rotated by the actuation of the alarm-train of the clock and the weights M M are thereby (by centrifugal force) brought into varying positions relative to the shaft the disk O will be moved longitudinally in a corresponding degree on the shaft fa.

P is an adjustable friction-block, against which the disk O is forced by movement of such disk in one direction on shaft a in the manner last above described. Friction-block P is mounted on the arm Q, and R is a thumbwheel by means of which the arm Q and friction-block P thereon are adjusted relative to the disk O. The desired speed to the cylinder C is thus obtained. l

S is an ordinary phonograph-record on cylinder C.

T is a rotatably-mounted post on which the sound -tube T and horn or trumpet z5 are mounted, as by the pivot to rotate with such post. A spring-actuated train in casing U is connected to the rotatable post T. Casing U may be secured to the clock-easing, as by standard U and screws a u.

' if isthe spring of the train in casing U.

lu is the main driving-wheel of the train. a" is a pinion on shaft wf, intermeshing with the main driving-wheel a3, and a is a gearwheel on shaft a, intermeshingl with pinion al on the rotatable post T.

IV hen the spring of the train is wound, as by key u, such spring will turn the post T,

so that the needle S of the phonographic reproducer S2 will follow the marks therefor on the record S and so that when such needle has passed off the record the post T will continue to turn, carrying the reproducer therewith until such needle of the reproducer again enters upon the lines therefor on the record to again repeat the words thereon.

V is a stop rigidly secured to the casing of the phonograph or to the sound-tubeof such phonograph, and V is a corresponding stop rigidly secured to the frame or case of the clock.

IV is an incline with which the stop V comes in contact in the rotation of the phonograph and sound-tube thereof around the axis of post T and whereby such stop, together with the phonograph-reproducer and especially the needle thereof, is raised just as such needle again enters onto the record used, and such incline is placed in front of the stop lV, so that as the rotation of the reproducer is arrested by stop V coming into contact with the stop V such reproducer may drop down onto the record, and as it so drops the stop V is carried down to pass out from under the stop V and the contents of the record be again spoken or shouted through the phonograph.

X is the setting-hand, indicating the time when the alarm-train is intended to be released.

X, Fig. 3, is a pivoted lever to be forced against wheel I and stop the action of thel alarm-train of the clock` Then the alarm is desired to be given at a certain time, the time-train and alarm-train of the clock are respectively wound, the hand X is set to the time the alarm is desired to go oii", and the needle S of the reproducer is placed on the record S adjacent to the stop V lVhen the alarm-train is released, the cylinder C is turned, together with the record S, and the words on the record are spoken or shouted from the reproducer S2 and trumpet t. As the cylinder C rotates when the spring of the train in casing U is wound, such train tends to turn standard T, so moving the needle S of the reproducer laterally on cylinder G, thus causing' such needle to readily follow the marks on record S. As needle S leaves the record the standard T continues to turn, thereby swinging the reproducer Si, sound-tube T', and trumpet t around until stop V rides up IIO incline IN and comes into contact with stop V"I or drops down off the incline IV, (thereby depositing needle S on record S at the beginnin of such record.) The contents of the record are thus repeated, with an interval of silence between such repetitions, until the spring of the alarm-train is run down or until the stop X is brought against wheel I to stop the train.

Having thus described my invention, its construction, and manner of operation, what I claim as new, and desire to secure by Letters Patent, is4
